CHARLES S. RIDER, OF SILVER. CREEK, NEW YORK, ASSIGNOR TO THE S. I-IOWES COMPANY, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent 1V0. 617,862, dated January 1'7, 1899. Application filed August 30, 1897. Serial No. 649,938. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES S. RIDER,-a citizenof the United States, residing at Silver Creek, in thecounty of Chautauqua and State of New York, have invented new and useful Improvements in Packing-Machines,of which the following is a specification.

This invention relates to that class of packing-machines which are more especially de- Io signed for packing flour and other pulverulent or granular material in small packages.

The object of this invention is to improve and simplify the tripping mechanism for this class of packing-machines, whereby the driving mechanism is reliably thrown into and out of gear during upward and downward movement of the platform.

In the accompanying-drawings, consisting of two sheets, Figure 1 is a vertical section Fig. 2 is a fragmentary side elevation of the tripping mechanism, on an enlarged scale, showing the position of the tripping mechanism during the packing operation. Fig. 3 is a similar view 2 5 showing the position of the tripping mechanism when the platform has been depressed to its lowest position. Fig. 4 is a horizontal section in line 4 4, Fig. 2. Fig. 5 is a fragmentary vertical section of the tripping mechanism in line 5 5, Fig. 2. v

Like letters of reference refer to like parts in the several figures.

A represents the main frame of the packing-Inachine, and B the horizontal table, ar-

' 3 5 ranged in the lower portion of the frame.

0 represents the supply hopper or bin, mounted on the upper portion of the frame and provided in its top with an inlet-opening c and at the outlet in its lower end with a D represents the feed-shaft, arranged vertically in the filling-tube and the hopper and provided-within the tube with auger-s d and within the hopper with stirrers d. This shaft is driven-from a horizontal driving-shaft E,

journaled in bearings e on the frame above the hopper by intermeshin g bevel gear-wheels e c secured to said shafts.

F is a clutch-wheel secured to the drivingshaft and provided with an external annular friction-face G is a constan tly-rotating clutch or driving 'pulley which is capable of rotary and longiin the direction for disengaging the clutch-- pulley fromthe clutch-wheel by a spring 71. secured to the frame and bearing against the horizontal arm h of the elbow-lever.

I represents the vertically-movableplatform which. supports the package to be filled and which is arranged on the upper end of a Y vertically-reciprocating lifting rod or bar '5. The latter slides in an upper guide 41', which is secured to the top of the table, and a lower guide i which is formed on a'bracket J, arranged below the table and secured to crossbars jj 0fthe frame. The platform when free is raised by a weight k, which is connected with a collar is on the lower end of the lifting-rod by a strap, cord, or chain passing around a roller'k supported on the under side of the table. The platform may be held in its lowest position by a spring bolt or catch l, which slides transversely in ways on the upper platform-guide and which engages with a notch Z in the upper portion of theliftingrod.

M represents a vertically-movable shiftingrod whereby the driving mechanism is coupled and uncoupled and which slides in a way m, arranged on one side of the bracket 5.

m is a rock-lever which is pivoted.between its arms to the under side of the table and which is connected with its outer armm by a rod m to the horizontal arm h of the elbowlever II and with its inner arm m to the upper end of the shifting-rod by a transverse pin n, passing through the rod and a slot in the lever. Upon raising this rod the driving mitting the rod to drop its weight, together with the tension of the spring h against the elbow-lever H, causes the clutch to be uncoupled. The shifting-rod is raised by a tappet '0, arranged on the lower end of the platform- This lever is pivoted by a horizontal pin or bolt p to the upper portion of thebracket J and is adapted to stand normally in a vertical position, so that its upper arm 10 engages with its end against the under side of the pin not? the shifting-rod, which serves as a shoulder and holds the shifting-rod in an elevated position. The trip-lever tends to swing constantly into its normal operative position by gravity, and this movement is expedited by a-rod .q, secured to the lower arm 10 of the trip-lever and provided with an adjustable weight g.

r is a stop arranged on the bracket J and engaging with the lower arm of the trip-lever when the upper arm thereof stands under the pm n.

S is a trip-arm which is mounted on the trip-lever and which is engaged at its inner end by a trip pin or projection s on the liftingrod when the package is filled, thereby turning the trip-lever into the direction of the arrow, Fig. 2, and uncoupling the clutch of the driving mechanism. The trip-arm is provided with a screw-threadedopening which receives a vertical adjusting screw T and with a bifurcated outer end .9, which embraces the lower arm of the trip-levei'j and prevents the trip-arm from turning with'the adj ustingscrew. The latter is journalerl in upper and lower bearings it on the lower arm of the trip-lever, but it is held against lengthwise movement therein by a head't and shoulder i on the screw bearing against opposite sides of the upper bearing.

The operation, briefly, of my improved packing-machine is as follows: Preparatory to starting the machine the platform is depressed to its lowest position, as shown in dotted lines in Fig. 1, and held there by the spring-bolt l, and the trip-lever is turned into the position shown in Fig. 3, whereby the shifting mechanism uncouples the drivinggear. An empty sack, bag, or other package is now placed around the filling-tube and the spring-bolt is withdrawn to permit the platform to rise and support the package at the bottom. During the last' portion of the up ward movement of the platform the tappeton the lifting-rod raises the shifting-rod so high that its pin or shoulder 11. passes above the upper end of the trip-lever, thereby permitting the latter to automatically swing under the pin and also throwing the clutch so that the angers turn and feed the material from the hopper into the package. As the filling of the package proceeds its weight increases and the platform gradually descends. The tappetis disengaged from the shifting-rod during the descent of the platform, but the shifting-rod isheld up by the trip-lever and the driving mechanism remains in gear. VVh'en the desired quantity of material has been fed into the package, the platform has descended to such an extent that the trip-pin on the lifting-rod strikes the trip-arm and turns the trip-lever, so as to liberate the shifting-rod and uncouple the driving-gear, thereby stopping the feed of material into the package. The operator now depresses the platform by hand until the spring-bolt engages with the notch in the lifting-rod, whereby the platform is held down for the purpose of replacing the filled package by an empty package, when the operation of filling the latter is repeated, as before described.

' I claim as my invention- The combination with the vertically-movable platform and the rod extending downwardly therefrom, the feed mechanism, the driving mechanism, and the clutch connecting the driving mechanism with the feed mechanism, of a vertical shifting-rod arranged on one side of said platform-rod and provided with a locking projection, a vertical way in which said shif tingrod is guided and in which it can descend by gravity, means whereby said shifting-rod is connected with the clutch, a zoo vertical trip-lever arranged on one side of the shifting-rod and having its upper arm projecting upwardly from its pivot and engaging under the projection of the shifting-rod when the latter is elevated, said trip-lever being provided below its pivot with a trip-arm which is depressed by a trip-pin on the platform-rod ing the shifting-rod and resetting the same and the trip-lever in elevating the platform, substantially as set forth.

\Vitness my hand this 29th day of J uly, 1897.

CHARLES s. RIDER.
